| Abstract | Alcaligenes eutrophus did not form the key enzymes of autotrophic metabolism, the soluble and particulate hydrogenases and ribulosebisphosphate carboxylase (RuBPC), during heterotrophic growth on succinate in batch cultures. During succinate-limited growth in a chemostat, high activities of both hydrogenases were observed. With decreasing dilution rate (D) the steady-state hydrogenase activity (H) followed first-order kinetics, expressed as follows: H = Hmax .e-alpha.D. An identical correlation was observed when autotrophic growth in a chemostat was limited by molecular hydrogen. During autotrophic growth under oxygen or carbon dioxide limitation, the activity if the soluble hydrogenase was low. These data suggested that hydrogenase formation depended on the availability of reducing equivalents to the cells. RuBPC activities were not correlated with the hydrogenase activities. During succinate-limited growth, RuBPC appeared at intermediate activities. During autotrophic growth in a carbon dioxide-limited chemostat, RuBPC was highly derepressed. RuBPC activity was not detected in cells that suffered from energy limitation with a surplus of carbon, as in a heterotrophic oxygen-limited chemostat, nor was it detected in cells limited in carbon and energy, as in the case of complete exhaustion of a heterotrophic substrate. From these data I concluded that RuBPC formation in A. eutrophus depends on two conditions, namely, carbon starvation and an excess of reducing equivalents. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
